Hereupon, the roll gap is decided so as to make the outer diameter at the exit of the stand M to be proportional to the designed reference cumulative drawing rate. This correction value for the roll gap is multiplied by the feedback factor proportional to the cumulative outer diameter drawing rate of the n-th stand, in consideration of the mutual influence of the drafts by the stands of odd numbers and of even numbers; hereby, the reference roll gap is corrected and the outer diameter and the roundness of the finished pipe are corrected.

IPC: G02B6/24
Filed: 1988-05-13
Abstract: PURPOSE:To improve the efficiency of a connecting operation and to shorten the connection time by arraying plural pieces of single optical fibers, holding the fibers in this state by means of a fiber holder and subjecting the fibers to simultaneous fusion slicing similarly to tape-shaped multiple optical fibers. CONSTITUTION:Plural pieces of the single optical fiber 7 are assumed to be arrayed and paralleled at a prescribed pitch.

The state in which these plural fibers 7 are paralleled at the prescribed pitch is thereupon, maintained if the fibers are put into this state and are then held by the fiber holder 6. Since the plural fibers 7 can be maintained in the state of arraying the same at the front ends by holding the fibers by the fiber holder 6 in such a manner, the fibers can be handled simultaneously in exactly the same manner as in case of holder the tape-shaped multiple optical fibers by the fiber holder 6 after the fiber holder 6 is mounted. The working efficiency is thereby improved and the time required before all of plural pieces of the single optical fiber are connected is extremely shortened.

Filed: 1979-09-11
Abstract: PURPOSE:To improve the efficiency of utilization of a memory unit by increasing the potential difference between pieces of cell information H and L by using a capacitor with no voltage dependency for cell capacity and by driving it via a storage word line. CONSTITUTION:As signal levels when word line W is selected, a high potential and intermediate potential are used. The high potential level is so set that while selection gate GT is completely turned on in a read of binary information stored in capacitor Cso8, the potential of bit line B will substantially be equalized to that of node S. Then, the intermediate potential level is set to an adequate value to turn off GT when the potential of line B after sense amplifiers 3 and 30 are activated is at the high level and to turn on it when at the low level. The potential of storage word line Z varies from the low potential to the high potential when line W is at the intermediate potential level and then varies from the high potential to the low potential after line W is unselected.

Title: Delay line filter with adaptive tap
Inventor: NOHARA TSUTOMU
IPC: H04B3/04
Filed: 1990-05-02
Abstract: PURPOSE:To increase the number of an adaptive tap coefficients without increasing a sampling period by dividing an adaptive device revising a filter coefficient into a front adaptive device and a rear adaptive device, and using the device selectively for each sampling period. CONSTITUTION:An adaptive tap is divided into a front adaptive device 20 and a rear adaptive device 21, and the adaptive tap coefficients are updated by selecting them alternately for each sampling period. The number of arithmetic operations for the adaptive device only is halved in comparison with a conventional device by devising the adaptive device into the front adaptive device 20 and the rear adaptive device 21. Since the number of arithmetic operations for the adaptive device only is decreased remarkably, the number of adaptive tap coefficients is increased without employment of high performance processors.
